Racial-Ethnic Differences in Patterns of Discontinuous Medication Treatment Among Medicaid-Insured Youths With ADHD

Medication adherence and persistence in children and adolescents with attention deficit hyperactivity disorder (ADHD): a systematic review and qualitative update

Low medication-adherence and persistence may reduce the effectiveness of ADHD-medication. This preregistered systematic review (PROSPERO CRD42020218654) on medication-adherence and persistence in children and adolescents with ADHD focuses on clinically relevant questions and extends previous reviews by including additional studies. We included a total of n = 66 studies. There was a lack of consistency in the measurement of adherence/persistence between studies. Pooling the medication possession ratios (MPR) and using the most common adherence definition (MPR ≥ 80%) indicated that only 22.9% of participants had good adherence at 12-month follow-up. Treatment persistence on medication measured by treatment duration during a 12-month follow-up averaged 170 days (5.6 months). Our findings indicate that medication-adherence and persistence among youth with ADHD are generally poor and have not changed in recent years. Clinicians need to be aware that various factors may contribute to poor adherence/persistence and that long-acting stimulants and psychoeducational programs may help to improve adherence/persistence. However, the evidence to whether better adherence/persistence contributes to better long-term outcomes is limited and requires further research.

Medicaid coverage continuity is associated with lymphoma stage among children and adolescents/young adults

ABSTRACT

Lymphoma is the third leading cause of cancer among children and adolescents/young adults (AYAs) in the United States, with later-stage diagnoses often being linked to worse outcomes. Continuous health insurance coverage is crucial for facilitating early cancer detection and diagnosis. Among Medicaid-insured children and AYAs diagnosed with lymphoma, this study examines whether the timing of Medicaid enrollment and coverage continuity are associated with stage at diagnosis. Using the Surveillance, Epidemiology, and End Results-Medicaid data, we identified children and AYAs (aged 0-39 years) newly diagnosed with lymphoma between 2007 and 2013 in 12 states that were linked to the administrative Medicaid data. Medicaid enrollment patterns were categorized into continuous Medicaid (preceding and through diagnosis), newly gained Medicaid (at or shortly after diagnosis), and other Medicaid enrollment patterns. Late-stage disease was defined as Ann Arbor stage IV (vs stage I-III). Multiple logistic regressions were estimated, with marginal effects (MEs) reported. Of 3524 patients identified, 37.8% had continuous Medicaid, followed by newly gained Medicaid (35.2%) and other Medicaid enrollment patterns (27.0%). Compared with patients continuously enrolled in Medicaid, those with newly gained Medicaid and with other Medicaid enrollment patterns were 54% (ME, 13.9 percentage points [ppt]; 95% confidence interval [CI], 8.5-19.2; P < .001) and 18% (ME, 4.6 ppt; 95% CI, 2.2-7.0; P < .001) more likely to present with stage IV lymphoma, respectively. Overall, having continuous Medicaid coverage before diagnosis was associated with a lower likelihood of late-stage lymphoma at diagnosis; however, only 3 in 8 Medicaid-insured children and AYAs with lymphoma were continuously enrolled in Medicaid before their diagnosis.

ADHD in Black Youth: A Content Analysis of Empirical Research from 1972 to 2023

OBJECTIVE

The purpose of this content analysis study was to characterize patterns of research on Black youth with ADHD.

METHOD

Relevant articles were identified through searching psychology and medical databases and cross-referencing citations in previously published review articles. The 204 empirical articles included in this study (1) were conducted in the United States, (2) had a predominantly child or adolescent sample, (3) had more than 80% Black youth/families in the study sample and/or conducted separate analyses for Black youth/families, and (4) examined ADHD symptoms or diagnoses. Articles were categorized into five primary content areas: Assessment, Treatment, Perceptions, Prevalence, and Associated Correlates. Journal characteristics, sample characteristics, and methodological characteristics are presented across these content areas.

RESULTS

Findings show a relatively low representation of Black youth with ADHD in the literature, with most studies using race comparative approaches and secondary data analyses, and many being published in medical journals.

CONCLUSION

Based on these results, changes are recommended both at the individual study and broader systems levels (e.g., funding agencies). More research, funding, and publications centering Black youth with ADHD are vital to understanding and correcting long-standing health disparities for this community.

Three-Year Effects of Motivational Interviewing-Enhanced Behavior Therapy for Adolescents With Attention-Deficit/Hyperactivity Disorder: A Randomized Community-Based Trial

OBJECTIVE

This study reports 3-year effects of a parent-teen cognitive/behavioral treatment for adolescent attention-deficit/hyperactivity disorder (ADHD), blended with Motivational Interviewing (Supporting Teens' Autonomy Daily [STAND]), vs Usual Care (UC) in 4 community clinics.

METHOD

This was a randomized clinical trial with double randomization of adolescents and therapists to STAND vs UC. Participants were 278 culturally diverse adolescents diagnosed with DSM-5 ADHD and 82 community therapists. Long-term effects on outcomes and theorized mechanisms were assessed at approximately 3 years post baseline (mean age = 16.94 years, SD = 1.69): ADHD severity (parent-rated), parent-teen conflict (parent/adolescent-rated), organization, time management, and planning skills (OTP; parent-rated), treatment and school enrollment (parent/adolescent-reported), and ADHD diagnostic persistence (clinician-determined). Therapist licensure was examined as a treatment moderator. Intent-to-treat (ITT) and per protocol analyses (n = 225; participants initiating treatment after agency intake) were conducted.

RESULTS

As in the original trial, ITT analyses indicated no long-term group by time effects. However, STAND (vs UC) led to superior long-term outcomes when therapists were licensed (22% of sample) vs unlicensed for parent-rated hyperactivity/impulsivity (d = 0.39; adolescent-rated parent-teen conflict: d = 0.27, and parent-rated OTP skills: d = 0.79). Previously reported post-treatment group differences on medication engagement were non-significant at the 3-year follow-up.

CONCLUSION

Although STAND did not outperform UC overall, group by licensure interactions indicate specific long-term impacts on ADHD symptoms, executive function skills such as OTP, and parent-teen conflict, extending this trial's acute effects and replicating previous findings. Clinicians in community settings might recommend adjunctive cognitive/behavioral treatment to adolescents with ADHD to maximize long-term outcomes. However, additional efforts are needed to facilitate effective implementation by unlicensed clinicians.

Prevalence of ADHD among Black Youth Compared to White, Latino and Asian Youth: A Meta-Analysis

OBJECTIVE

To systematically review the prevalence of Attention Deficit Hyperactivity Disorder (ADHD) among Black children and adolescents compared to White, Latino and Asian children and adolescents.

METHOD

Peer-reviewed articles were identified in seven databases and included if they reported prevalence of ADHD among Black children and adolescents living in a minority context and compared rates to at least one of White, Latino or Asian samples. A total of 7050 articles were retrieved and 155 articles were subjected to full evaluation. Twenty-three studies representing 26 independent samples were included.

RESULTS

The pooled sample size was n = 218,445 (k = 26), n = 835,505 (k = 25), n = 493,417 (k = 24), and n = 66,413 (k = 7) of Black, White, Latino, and Asian participants, respectively. Pooled prevalence rate of ADHD was 15.9% (95%CI 11.6% - 20.7%) among Black children and adolescents, 16.6% (95%CI 11.6% - 22.2%) among Whites, 10.1% (95%CI 6.9% - 13.8%) among Latinos and 12.4% (95%CI 1.4% - 31.8%) among Asians. There was no significant difference in prevalence between ethnic groups, whereas both Black and White children and adolescents had marginally statistically significant higher prevalence than Asians. The results of a meta-regression analysis showed no moderating effects of the type of sample and the year of publication of studies. A significant publication bias was observed, suggesting that other moderators were not identified in the present systematic review.

CONCLUSION

In contrast to the assertion in the DSM-5 that clinical identification among Black children and adolescents is lower than among White children and adolescents, the present meta-analysis suggests similar rates of ADHD among these two groups. The importance of considering cultural appropriateness of assessment tools and processes is emphasized.

Mental Health Care Utilization Among Parents of Children With Cancer

Importance

Caring for children diagnosed with cancer may adversely affect the mental health (MH) of parents.

Objective

To characterize utilization of MH services among parents of children with vs without cancer using nationwide commercial claims data.

Design, Setting, and Participants

For this cross-sectional study, the Merative MarketScan Commercial Claims Database was used to identify continuously insured families of children treated for cancer (aged ≤21 years at diagnosis) during 2010 to 2018, compared with families who matched eligibility criteria but did not have a child with a cancer history. Parents were assessed from 18 months before to 12 months after their child's cancer diagnosis. Analyses were conducted from February 2022 to September 2023.

Exposures

Children's cancer diagnosis.

Main Outcomes and Measures

Outcomes included parents' MH-related visits during the first year following their child's cancer diagnosis. Logistic regressions compared outcomes between families of children with vs without cancer, adjusting for sociodemographic and clinical factors.

Results

This study included 4837 families of children with cancer (4210 mothers and 4016 fathers) and 24 185 families of children without cancer (21 444 mothers and 19 591 fathers) with continuous insurance enrollment. Most household leads were aged 35 to 54 years (3700 [76.5%] in families of children with cancer vs 17 812 [73.6%] in families of children without cancer) and resided in urban areas (4252 [87.9%] vs 21 156 [87.5%]). The probabilities of parents having anxiety-related visits (10.6% vs 7.0%), depression-related visits (8.4% vs 6.1%), and any MH-related visits (18.1% vs 13.3%) were higher in families of children with vs without cancer. Adjusted analyses showed absolute increases of 3.2 percentage points (95% CI, 2.3 to 4.0; 45.7% relative increase), 2.2 percentage points (95% CI, 1.4 to 3.0; 36.1% relative increase), and 4.2 percentage points (95% CI, 3.1 to 5.3; 31.3% relative increase) in the probabilities of 1 or both parents having anxiety-related visits, depression-related visits, and any MH-related visits, respectively, among families of children with vs without cancer. Such differences were greater in magnitude among mothers than fathers.

Conclusions and Relevance

In this cohort study of privately insured parents, those caring for children with cancer had a higher likelihood of utilizing MH care than other parents. These findings underline the importance of interventions toward targeted counseling and support to better meet MH care needs among parents and caregivers of children with cancer.

Screening for parent and child ADHD in urban pediatric primary care: pilot implementation and stakeholder perspectives

BACKGROUND

ADHD commonly co-occurs in children and parents. When ADHD is untreated in parents, it contributes to negative child developmental and treatment outcomes. Screening for parent and child ADHD co-occurrence in pediatric primary care may be an effective strategy for early identification and treatment. There is no data on whether this screening model can be implemented successfully and there exists limited guidance on how to effectively approach parents about their own ADHD in pediatric settings. Even greater sensitivity may be required when engaging with families living in urban, low SES communities due to systemic inequities, mistrust, and stigma.

METHODS

The current pilot study described the first 6 months of implementation of a parent and child ADHD screening protocol in urban pediatric primary care clinics serving a large population of families insured through Medicaid. Parents and children were screened for ADHD symptoms at annual well-child visits in pediatric primary care clinics as part of standard behavioral health screening. Independent stakeholder group meetings were held to gather feedback on factors influencing the implementation of the screening and treatment strategies. Mixed methods were used to examine initial screening completion rates and stakeholder perspectives (i.e., parents, primary care office staff, pediatricians, and behavioral health providers) on challenges of implementing the screening protocol within urban pediatric primary care.

RESULTS

Screening completion rates were low (19.28%) during the initial 6-month implementation period. Thematic analysis of stakeholder meetings provided elaboration on the low screening completion rates. Identified themes included: 1) divergence between provider enthusiasm and parent hesitation; 2) parent preference versus logistic reality of providers; 3) centering the experiences of people with marginalized identities; and 4) sensitivity when discussing parent mental health and medication.

CONCLUSIONS

Findings highlight the importance of developing flexible approaches to screening parent and child ADHD in urban pediatric health settings and emphasize the importance of cultural sensitivity when working with marginalized and under-resourced families.

Can We Expand the Pool of Youth Who Receive Telehealth Assessments for ADHD? Covariates of Service Utilization

BACKGROUND

During the COVID-19 pandemic, telehealth became widely utilized for healthcare, including psychological evaluations. However, whether telehealth has reduced or exacerbated healthcare disparities for children with Attention-Deficit/Hyperactivity Disorder (ADHD) remains unclear.

METHODS

Data (race, ethnicity, age, insurance type, ADHD presentation, comorbidities, and distance to clinic) for youth with ADHD (Mage = 10.97, SDage = 3.42; 63.71% male; 51.62% White) were extracted from the medical record at an urban academic medical center. Three naturally occurring groups were compared: those evaluated in person prior to COVID-19 (n =780), in person during COVID-19 (n = 839), and via telehealth during COVID-19 (n = 638).

RESULTS

Children seen via telehealth were significantly more likely to be older, White, have fewer comorbid conditions, and live farther from the clinic than those seen in person.

CONCLUSIONS

The current study suggests that telehealth has not eliminated barriers to care for disadvantaged populations. Providers and institutions must take action to encourage telehealth use among these groups.

Racial and Ethnic Disparities in Childhood ADHD Treatment Access and Utilization: Results From a National Study

OBJECTIVE

The study examined racial-ethnic disparities in access to and utilization of treatment for attention-deficit hyperactivity disorder (ADHD) and other psychiatric diagnoses among children with ADHD.

METHODS

Nationally representative, cross-sectional data from the Household Component of the Medical Expenditure Panel Survey 2011-2019 were used to examine racial-ethnic disparities in access to and utilization of treatment by children ages 5-17 with ADHD (N=5,838). Logistic regression models were estimated for access outcomes, and generalized linear models were estimated for utilization outcomes. Multivariable regression models adjusted for race-ethnicity, age, sex, and treatment need in accordance with the Institute of Medicine definition of health care disparities.

RESULTS

In adjusted analyses, compared with White children with ADHD, Black, Hispanic, and Asian children with ADHD had significantly lower rates of any past-year treatment visit for ADHD or for other psychiatric diagnoses. They also had lower rates of having accessed ADHD medication. Compared with White children, Black and Asian children with ADHD used fewer ADHD medications, and Black and Hispanic children with ADHD had lower overall mental health treatment expenditures.

CONCLUSIONS

Disparities in ADHD treatment among children from racial-ethnic minority populations may be driven primarily by disparities in access rather than in utilization. Once treatment had been accessed, disparities in utilization were largely accounted for by differences in socioeconomic status. These findings suggest that interventions targeting access to treatment among children from racial-ethnic minority populations may help close existing care gaps.

Narrowing Insurance Disparities Among Children and Adolescents With Cancer Following the Affordable Care Act

Despite advances toward universal health insurance coverage for children, coverage gaps remain. Using a nationwide sample of pediatric and adolescent cancer patients from the National Cancer Database, we examined effects of the Affordable Care Act (ACA) implementation in 2014 with multinomial logistic regressions to evaluate insurance changes between 2010-2013 (pre-ACA) and 2014-2017 (post-ACA) in patients aged younger than 18 years (n = 63 377). All statistical tests were 2-sided. Following the ACA, the overall percentage of Medicaid and Children's Health Insurance Program-covered patients increased (from 35.1% to 36.9%; adjusted absolute percentage change [APC] = 2.01 percentage points [ppt], 95% confidence interval [CI] = 1.31 to 2.71; P < .001), partly offset by declined percentage of privately insured (from 62.7% to 61.2%; adjusted APC = -1.67 ppt, 95% CI = -2.37 to -0.97; P < .001), leading to a reduction by 15% in uninsured status (from 2.2% to 1.9%; adjusted APC = -0.34 ppt, 95% CI = -0.56 to -0.12 ppt; P = .003). The largest declines in uninsured status were observed among Hispanic patients (by 23%; adjusted APC = -0.95 ppt, 95% CI = -1.67 to -0.23 ppt; P = .009) and patients residing in low-income areas (by 35%; adjusted APC = -1.22 ppt, 95% CI = -2.22 to -0.21 ppt; P = .02). We showed nationwide insurance gains among pediatric and adolescent cancer patients following ACA implementation, with greater gains in racial and ethnic minorities and those living in low-income areas.

Rise, and pronounced regional variation, in methylphenidate, amphetamine, and lisdexamfetamine distribution in the United States

BACKGROUND

The prescription stimulants methylphenidate, amphetamine, and lisdexamfetamine are sympathomimetic drugs with therapeutic use. They are designated in the United States as Schedule II substances, defined by the 1970 Controlled Substances Act as having a "high potential for abuse". Changing criteria for the diagnosis of Attention Deficit Hyperactivity Disorder in 2013 and the approval of lisdexamfetamine for binge eating disorder in 2015 may have impacted usage patterns. This report compared the pharmacoepidemiology of these stimulants in the United States from 2010-2017.

METHODS

Distribution of amphetamine, methylphenidate, lisdexamfetamine were examined via weights extracted from the Drug Enforcement Administration's (DEA) Automated Reports and Consolidated Ordering System (ARCOS). Median stimulant Daily Dosage per patient was determined for a regional analysis. The percent of cost and prescriptions attributable to each stimulant and atomoxetine in Medicaid from the "Drug Utilization 2018 - National Total" from the Centers for Medicare and Medicaid was determined.

RESULTS

There was a rise in amphetamine (+67.5%) and lisdexamfetamine (+76.7%) from 2010-2017. The change in methylphenidate (-3.0%) was modest. Persons/day stimulant usage was lower in the West than in other US regions from 2014-2017. There was a negative correlation (r(48) = -0.43 to -0.65, p < .05) between the percent Hispanic population per state and the Daily Dosage/population per stimulant. Methylphenidate formulations accounted for over half (51.7%) of the $3.8 billion reimbursed by Medicaid and the plurality (45.4%) of the 22.0 million prescriptions. Amphetamine was responsible for less than one-fifth (18.4%) of cost but one-third of prescriptions (33.6%). Lisdexamfetamine's cost (26.0%) exceeded prescriptions (16.3%).

CONCLUSION

The rising amphetamine and lisdexamfetamine distribution may correspond with a rise in adult ADHD diagnoses. Regional analysis indicates that stimulant distribution in the West may be distinct from that in other regions. The lower stimulant distribution in areas with greater Hispanic populations may warrant further study.

Diagnostic and Medication Treatment Disparities in African American Children with ADHD: a Literature Review

BACKGROUND

Despite a national focus on achieving health equity, limited attention has been paid to behavioral and pediatric health disparities. As the most common pediatric neurobehavioral disorder, attention-deficit/hyperactivity disorder (ADHD) provides an opportunity to assess the status of pediatric behavior health disparities. The purpose of this literature review is to provide a synthesis of existing research on ADHD diagnostic and treatment disparities between African American and White children.

METHODS

Studies were systematically identified through searches in PubMed, CINAHL, and APA PsycInfo using the terms attention-deficit/hyperactivity disorder, disparity, race, ethnicity, diagnosis, medication, and treatment. Summary calculations were conducted to report the proportions of studies with statistically significant differences in ADHD diagnosis and treatment between White and African American children, and to describe trends in disparities over time.

RESULTS

Forty-one studies were included in this review. The majority of studies identified significant disparities in ADHD diagnosis and medication treatment between African American and White children. While diagnostic disparities show a trend toward reduction over time, a similar trend was not observed in medication treatment disparities. This synthesis provides a critique of the existing literature and recommendations for practice and future research.

Racial disparities in medication use: imperatives for managed care pharmacy

The COVID-19 pandemic and the social unrest pervading U.S. cities in response to the killings of George Floyd and other Black citizens at the hands of police are historically significant. These events exemplify dismaying truths about race and equality in the United States. Racial health disparities are an inexcusable lesion on the U.S. health care system. Many health disparities involve medications, including antidepressants, anticoagulants, diabetes medications, drugs for dementia, and statins, to name a few. Managed care pharmacy has a role in perpetuating racial disparities in medication use. For example, pharmacy benefit designs are increasingly shifting costs of expensive medications to patients, creating affordability crises for lower income workers, who are disproportionally persons of color. In addition, the quest to maximize rebates serves to inflate list prices paid by the uninsured, among which Black and Hispanic people are overrepresented. While medication cost is a foremost barrier for many patients, other factors also propagate racial disparities in medication use. Even when cost sharing is minimal or zero, medication adherence rates have been documented to be lower among Blacks as compared with Whites. Deeper understandings are needed about how racial disparities in medication use are influenced by factors such as culture, provider bias, and patient trust in medical advice. Managed care pharmacy can address racial disparities in medication use in several ways. First, it should be acknowledged that racial disparities in medication use are pervasive and must be resolved urgently. We must not believe that entrenched health system, societal, and political structures are impermeable to change. Second, the voices of community members and their advocates must be amplified. Coverage policies, program designs, and quality initiatives should be developed in consultation with those directly affected by racial disparities. Third, the industry should commit to dramatically reducing patient cost sharing for essential medication therapies. Federal and state efforts to limit annual out-of-pocket pharmacy spending should be supported, even though increased premiums may be an undesirable (yet more equitable) consequence. Finally, information about race should be incorporated into all internal and external reporting and quality improvement activities.

Training Psychiatrists to Achieve Mental Health Equity

This article highlights the history of the psychiatric training practices that have contributed to inequity in mental health service delivery, particularly to underserved populations. It discusses current training practices that may be effective at reducing such disparities, suggests policy recommendations to increase the number of underrepresented minorities in health services, and makes recommendations for the further development and implementation of training practices that address health inequity. The article reviews issues in both general psychiatry and child/adolescent training in addition to lifelong learning needs.

Challenges in ADHD care for ethnic minority children: A review of the current literature

While attention deficit hyperactivity disorder (ADHD) has been extensively studied in the past decades, the role of social and cultural practices in its assessment, diagnosis, and treatment has been often overlooked. This selective review provides an overview of research that explores social and cultural influences on help-seeking behavior in ethnic minority children with ADHD. Studies were selected that address cultural diversity in three areas of ADHD help-seeking: problem recognition, access to mental health services, and treatment. Special attention was given to studies of treatment selection and adherence in minority groups. Findings suggested that cultural disparities in ADHD care among ethnic minority children occur in the early stages of problem recognition, through service selection, and in the quality of treatment. Ethnic minority children were less likely than their nonminority counterparts to be diagnosed with ADHD and its comorbid conditions and less likely to be prescribed and adhere to stimulant drug treatment. These differences reflect cultural diversity in norms and attitudes towards mental health issues (e.g., fear of social stigma) as well as limited access to qualified health care. Paradoxically, cultural, racial, and language bias may also lead to the overidentification of ethnic minority children as disabled and to higher ratings of ADHD symptoms. This review highlights the importance of sociocultural factors in understanding developmental psychopathology and help-seeking behavior. In addition, it further supports calls for increasing cultural competence in communications during clinical assessment, diagnosis, and treatment in minority communities. Clinical, theoretical, and methodological considerations for future research are discussed.

A Commercial Insurance Claims Analysis of Correlates of Behavioral Therapy Use Among Children With ADHD

OBJECTIVE

The study examined factors associated with uptake of behavioral therapy among children with attention-deficit hyperactivity disorder (ADHD).

METHODS

Insurance claims data from 2008-2014 (MarketScan) were reviewed to examine associations between behavioral therapy use and demographic, patient, family, and provider factors. The association between ADHD medication use and future uptake of behavioral therapy was examined with logistic regression adjusted for covariates found to affect behavioral therapy use.

RESULTS

Among 827,396 youths with ADHD, under 50% received any billable behavioral therapy services over the 7 years. ADHD severity, gender, region of residence, assessment year, comorbid behavioral disorders, and behavioral therapy use by siblings were significantly associated with behavioral therapy use (p<0.001). Parent psychopathology and sibling medication use was not. Children prescribed ADHD medication were 2.5 times less likely than those not prescribed medication to use behavioral therapy, even after adjustment for severity of behavioral health symptoms and other covariates (odds ratio [OR]= 0.41, 95% confidence interval [CI]=.40-.41, p<0.001). Effects of medication use were stronger for future uptake of behavioral therapy (OR=0.25, 95% CI =0.24-0.25, p<.001). The impact of medication use on behavioral therapy use was equally strong for children under age 6 and for older children and did not weaken after release of 2011 guidelines recommending behavioral therapy as the initial ADHD treatment for young children.

CONCLUSIONS

Multiple systems, family, patient and provider factors affected behavioral therapy uptake. ADHD medication was a robust and potentially modifiable factor. It may be advisable to engage families in behavioral therapy prior to initiation of ADHD medication.

Evidence of Low Adherence to Stimulant Medication Among Children and Youths With ADHD: An Electronic Health Records Study

OBJECTIVE

The objective of this study was to evaluate rates and correlates of stimulant medication adherence in a sample of pediatric patients using data derived from electronic medical records (EMRs) from a large health care organization in a large metropolitan area. The study relied on a novel definition of medication adherence as a timely renewal of an index prescription determined using the electronically recorded issuance of a stimulant prescription in the EMR ("refill").

METHODS

Prescription and sociodemographic data were extracted from the Partners HealthCare Research Patient Data Registry to calculate adherence to stimulant medication treatment.

RESULTS

In the EMR, 2,206 patients with prescriptions for central nervous system stimulant medication were identified. Results showed that 46% of the index prescriptions were refilled within the timeframe necessary for the patient to be considered consistently medicated. A multivariable logistic regression model predicting medication adherence from patient demographic and treatment characteristics yielded an area-under-the-curve statistic of 0.57, indicating that these characteristics predicted adherence only modestly better than chance.

CONCLUSIONS

EMR data from a large health care organization showed that 46% of pediatric patients were adherent to treatment with stimulants. Rates of medication adherence were worse among patients receiving care from a primary care provider than among those receiving care from a psychiatrist, in older patients, and in female patients and did not appear to be influenced by racial-ethnic group, economic class, stimulant type, or medication formulation (short or long acting). These findings, which show low rates of medication adherence among children and adolescents with ADHD, suggest the need for efforts to improve these rates.

Prior Authorization Policies and Preferred Drug Lists in Medicaid Plans: Stakeholder Perspectives on the Implications for Youth with ADHD

This qualitative study describes how Medicaid policies create challenges for the delivery and receipt of mental health treatment for low-income youth in Georgia. We conducted focus groups with caregivers of Medicaid-enrolled children with ADHD and semi-structured interviews with providers and administrators at four safety net clinics that provided mental health care to these youth. Stakeholders reported that prior authorization policies for psychosocial services, restrictiveness of preferred drug lists, and changes in preferred drug lists in Medicaid plans created barriers to treatment continuity and quality for youth with ADHD and led to more administrative burden for safety-net clinics serving these youth.

Adherence to Recommended Care Guidelines in the Treatment of Preschool-Age Medicaid-Enrolled Children With a Diagnosis of ADHD

OBJECTIVE

Attention-deficit/hyperactivity disorder (ADHD) is the most common neurodevelopmental disorder of childhood. Clinical guidelines recommend behavior therapy as the first-line treatment for preschool-age children with ADHD. This study evaluated longitudinal patterns of services received by Medicaid-enrolled children ages 2 to 5 with ADHD in seven southeastern states (Alabama, Florida, Georgia, Louisiana, Mississippi, North Carolina, and South Carolina).

METHODS

A discrete sequence clustering analysis was used with 2005-2012 Medicaid Analytic eXtract data to profile patient-level utilization for each state, with a focus on receipt of psychological services and medication. The model output was used to assess utilization behaviors longitudinally relative to recommended care guidelines and to characterize sources of variation in utilization patterns by demographic and ecological factors.

RESULTS

Five states had a utilization profile with a high probability of receipt of psychological services before medication among children with ADHD, covering 16% of the total study population. Most young children's ADHD care experience in the seven states (65%) fit utilization profiles characterized by a high probability of receiving any ADHD medication. Black race was significantly associated with higher utilization of psychological services in three states.

CONCLUSIONS

About 16% of Medicaid-enrolled preschool-age children with ADHD received care during 2005-2012 that appeared to be consistent with 2011 recommended care guidelines. State-level and subpopulation variations in utilization for ADHD-related clinical care were found. The findings indicate that there were major gaps in treatment for ADHD among young children and that the gaps are wider for some states and subpopulations of children.

Trends in use of prescription stimulants in the United States and Territories, 2006 to 2016

BACKGROUND

Stimulants are considered the first-line treatment for Attention Deficit Hyperactivity Disorder (ADHD) in the US and they are used in other indications. Stimulants are also diverted for non-medical purposes. Ethnic and regional differences in ADHD diagnosis and in stimulant use have been identified in earlier research. The objectives of this report were to examine the pharmacoepidemiological pattern of these controlled substances over the past decade and to conduct a regional analysis.

METHODS

Data (drug weights) reported to the US Drug Enforcement Administration's Automation of Reports and Consolidated Orders System for four stimulants (amphetamine, methylphenidate, lisdexamfetamine, and methamphetamine) were obtained from 2006 to 2016 for Unites States/Territories. Correlations between state level use (mg/person) and Hispanic population were completed.

RESULTS

Amphetamine use increased 2.5 fold from 2006 to 2016 (7.9 to 20.0 tons). Methylphenidate use, at 16.5 tons in 2006, peaked in 2012 (19.4 tons) and subsequently showed a modest decline (18.6 tons in 2016). The consumption per municipality significantly increased 7.6% for amphetamine and 5.5% for lisdexamfetamine but decreased 2.7% for methylphenidate (all p < .0005) from 2015 to 2016. Pronounced regional differences were also observed. Lisdexamfetamine use in 2016 was over thirty-fold higher in the Southern US (43.8 mg/person) versus the Territories (1.4 mg/person). Amphetamine use was about one-third lower in the West (48.1 mg/person) relative to the Northeastern (75.4 mg/person, p < .05) or the Midwestern (69.9 mg/person, p ≤ .005) states. States with larger Hispanic populations had significantly lower methylphenidate (r(49) = -0.63), lisdexamfetamine (B, r(49) = -0.49), and amphetamine (r(49) = -0.43) use.

CONCLUSIONS

Total stimulant usage doubled in the last decade. There were dynamic changes but also regional disparities in the use of stimulant medications. Future research is needed to better understand the reasons for the sizable regional and ethnic variations in use of these controlled substances.
